How this compares with published guidance
200 mg or more At 422 mg potassium per serving, this is at or above the 200 mg line that the National Kidney Foundation (Potassium in Your CKD Diet, updated May 5, 2023) generally calls high potassium per serving.
The 200 mg line applies to a serving, and the serving here is the USDA household portion listed above, which may not match the serving size used on other lists. NKF gives no daily potassium target. Your own limit comes from your care team.
Phosphorus. NKF (Phosphorus and Your CKD Diet) gives no per-serving cutoff, so no label is applied to 26 mg. See where it sits on the phosphorus ranking.
Phosphorus additives matter for processed versions: NKF says phosphorus from additives is completely absorbed. A prepared or packaged version of this food may differ from the USDA value above.
